Version 0.7.2
It's fine. The storytelling is overall pretty standard, but serviceable enough. The plot is nothing great, but it gives enough of a credible setting for the MC to do dimension-hopping and meet all those alien characters. A bit dissapointed some (all?) of them are characters from other franchises, rather than unique monsters to this game, but that's a personal gripe.
The problems I have with it are more with this gameplay elements, funnily enough, rather than its storytelling. I've never liked how Twine doesn't allow more than 10 save files; I don't know if the dev can change the amount, but since that kind of game requires you to reload quite often, it can be a pain in the ass to see all the content in one go.
So for starters, your charater has multiple different stats that indicate what kind of outcome you will get out of each scenario; if you're strong enough, you can do X, or else Y. Typical stuff. The problem is the game will not tell you upfront how much of each stat you actually need to complete a quest, until you buy a very specific item and read a book in the library about each quest, and even that info is incomplete. There are also some locked stats you can't level up, unless you already have a point or two into that category.
How do you get a point in those stats without the starting class? I don't know. The game will never tell you about these things. It's very easy to get locked out of a route late in the game because you didn't invest correctly, forcing you to start over multiple times for a very minor decision you made early in the game.
And none of the quests are repeatable. If you screwed up once, you either reload at a very early point in your run or you give up that monster althogether. You'll want to spend as much time and money as possible leveling up your character before accepting the quest, because you can't accept them all at once. But actually getting money is difficult, because those quests are finite in number and there's only so many points you can attribute. Once you've invested in a trait, you'll probably need to create another character to do another quest, and rince and repeat until you unlock them all.
Not only is this tedious, but some of those stats are just straight up useless. Karma and Charisma are used very sparingly and only for some characters that need multiple interactions to develop their content; in that meantime, it's very easy to screw up your stat investment and get locked out of their route halfway through unknowingly.
But the worst thing about these stats, is they actually don't help you get adult scenes; they actually lock you out of most of them. If you try to be a good guy and help those monsters, most of the time you'll just go home blue balled, so the best way to get them is to be an ass and invest in fighting for most of them. So most of that content is rape or at least non-con. I don't have an issue with that, and there's also some wholesome stuff, but I wish the game was more upfront about what kind of content it has, so that I knew before investing in the wrong stats for an hour.
It's still a fun game, and most of those adult scenes are pretty hot, but there's a lot of rookie mistakes here that bog the whole thing down.
